Smart Bulbs and Lighting Technologies

The video tutorial explores six main types of light bulbs: incandescent, standard fluorescent, compact fluorescent (CFL), halogen, light-emitting diode (LED), and smart bulbs. It discusses their characteristics, energy efficiency, and suitable applications. Incandescent bulbs, developed by Thomas Edison, are inefficient and phased out. Fluorescent bulbs are long-lasting, while CFLs are energy-efficient but contain mercury. Halogen bulbs mimic natural light, and LEDs are the most energy-efficient. Smart bulbs, often LED-based, offer remote control via Wi-Fi.
